The Atlanta market

The City of Atlanta Office of Buildings lists replacing a water heater as plumbing permit work. For existing one- and two-family homes, its exempt list includes repair or replacement of existing air conditioner condensers, but only repair of existing furnaces, so a full furnace replacement is unclear and worth a call. Heat pumps are not addressed. A Georgia-licensed plumbing contractor or the legal owner (signing a homeowner affidavit) may apply, and an adult must be home to let the inspector in. The trade permit form lists $40 per heating system and $40 per cooling system up to 5 tons, plus a $150 minimum base fee whose application to single-family homes is not confirmed. Cooling dominates: EIA counts central air in 86% of Georgia homes and heat pumps as main heat in 27%. Sandy Springs, Roswell, DeKalb and Cobb run separate permit offices.

Furnaces are the main heat in 60% of Georgia homes, usually gas units in attics or crawlspaces paired with a central AC coil. Because the furnace and coil share a cabinet, replacing one raises questions about the other. Ask how old the coil is and whether it fits the new furnace. Attic equipment sweats through Atlanta summers. With a high-efficiency furnace, which makes its own condensate, ask about the drain line and a secondary pan so a clog drips into a tray and stays off the drywall.
